How much coffee to buy each week for your household
November 26, 2026 · 2 min read
Count about 10 grams of coffee per cup. Multiply by the number of cups your household drinks a day, then by seven, and that is what you need each week. Buying that amount, and not much more, is what keeps your coffee fresh.
The formula
People × cups a day × 7 × 10 grams = coffee per week
Ten grams is roughly two level tablespoons of ground coffee, for a cup of about 200 ml. If your household uses big mugs, count 15 grams per mug.
Quick reference
| Household | Cups a day per person | Coffee per week | What to ask for |
|---|---|---|---|
| 1 person | 1 | 70 g | A quarter kilo, lasts about 3 weeks |
| 1 person | 2 | 140 g | A quarter kilo, lasts about 12 days |
| 2 people | 2 | 280 g | Half a kilo, lasts about 12 days |
| 3 people | 2 | 420 g | Half a kilo, lasts a little over a week |
| 4 people | 2 | 560 g | One kilo, lasts about 12 days |
| 4 people | 3 | 840 g | One kilo, lasts a little over a week |
Adjustments worth making
- Weekends: if you drink more on Saturday and Sunday, add a day to the count.
- Guests: count two extra cups for each guest who comes for breakfast.
- Café de olla: it usually takes a bit more coffee per cup, so add 20% to the total.
- Strong coffee: if you like it strong, count 12 or 13 grams per cup instead of 10.
Why not buy more
A kilo seems more practical than coming in every week. The problem is that after six to eight weeks the coffee starts to lose its aroma. If your count covers a month or less, you are drinking coffee at its best.
